Alternative therapies in cancer treatment

Dear Dr. Roach: I wonder why you never talk about holistic measures to prevent illnesses, such as cancer. I just read an article by an oncologist who said there are certain anti-cancer supplements that work, including vitamin D, magnolia extract and artichoke extract, all of which have been shown in laboratory studies to kill a variety of cancer cells, including colon, breast and liver cancers, and leukemia. Artichoke extract also contains cynarin, which decreases inflammation.
